Hi sifus

My Z250 factory chain has kaput after 33,000km. Anyone has experience with these two chain models?

D.I.D. 520VX3 & RK GB520KRX

Both seems to be using X-Ring type chains. but for RK, they bundle both the Sprocket & Chain for the same price of just the DID chains.

Would you personally go with (RK Sprocket + DID chains) or just go for (RK Sprockets & Chains) or do you guys have any other recommendations based off experience?

Any comments and recommendations will be highly appreciated!

520VX3 is overkill for the Z250

Used rk on my old z250...lasted quite awhile....i lube every week n wash once a week.

Never used did before though.

N for ur factory chain kaput at 33k km...u need to better maintain ur chain...kawasaki chains can last really long if looked after.... N aftermarket chain will not last aslong as the factory chain even if looked after the same way.

o-ring chain rivet type is more than enough for your bike.
cant go wrong between rk and did, get whichever is cheaper.
proper maintenance is more important.

okay, guess I'll just go with the RK Chain Sprocket combo since it's cheaper than DID chain itself.

TS, borrow your topic.

anyone can suggest chain and sprocket for yamaha XJ6 use ?
go for RK or D.I.D ?

DID

250cc O ring already sufficient...no need X ring. both are OK just need to properly maintain the chain

DID can last longer compare to RK with good maintenance ?

it doesn't stretch as RK

The DID 525VX3 Pro-Street X-Ring chain has an average tensile strength of 9,980 lbs

The RK 525GXW XW-Ring chain has a tensile strength of 9,300 pounds
The RK 525ZXW XW-Ring chain has a tensile strength of 10,400 pounds

alright, thx for the info bro

To be honest, I just get the cheapest x ring chain for my bike. It's a once a year replacement anyway as I do 30+k per year. To be fair I'm not that conscientious about chain maintenance on a daily dike that gets wet often. I just replace it once the links get kinked up or stretches beyond 3 adjustments.

My OEM O ring DiD chain on my NK lasted about 25k before I replaced it with a RK x ring 520. Tbh, I don't expect the RK to last beyond 30k either. For 180 a set, I just factor it in my annual maintenance cost. For my usage, I change the sprocket for every 2 chains

where you change ur chain, recommend pls

Any big bike shop can change a chain. Just make sure they rivet it to spec

Sian motor asking for money already. My 428 chain now clunking cannot dissapear anymore even after put chain lube. Only 54k++ and chain already spoil somemore its RKM O ring
